Abstract
The utility model provides a novel thread off prevention anti-torsion sucker rod, belonging to an oil-pumping part used in an oil field. The sucker rod has an oil-pumping rod body, wherein, one end of the oil-pumping rod body is provided with an upper joint with external thread, while the other end is provided with a lower joint with external thread; the upper joint is provided with a convex block, while the lower joint is provided with a groove corresponding to the convex block. Two sucker rods are connected together through the convex block and the groove, and the joints of both sucker rods are provided with couplings outside; when the utility model is used, the convex block and the groove connected together through inserting bear torsional force, thereby avoiding the phenomena of thread off and twisting off; therefore, the utility model prolongs the service life of the sucker rod and avoids the problems such as underground salvage due to the sucker rod falling underground caused by thread off or twisting off.
Description
Technical field
The utility model provides a kind of oil field oil pumping parts, especially a kind of sucker rod.
Background technology
At present, an end of the sucker rod of oil field oil pumping usefulness is for having externally threaded joint, and the other end is the box cupling that has internal thread.During installation, joint on sucker rod and the box cupling on another root sucker rod are by being threaded togather.The antitorque anticreep poor performance of this sucker rod.In use, owing to reasons such as hole deviations, sucker rod can afford torsion.This torsion can make and produce forward twisting or oppositely twisting between joint and the box cupling screw thread, the problem that gets loose when oppositely twisting even thread off, and forward can cause the sucker rod distortion even be twisted off when twisting.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel antitorque anticreep sucker rod, to prevent to occur in the sucker rod use threading off, twisting off phenomenon.
The utility model is achieved in that the antitorque sucker rod of novel anticreep, and it has the oil pumping body of rod, and the oil pumping body of rod one end has projection for being with externally threaded top connection, the other end for being with externally threaded lower contact in the top connection, have in the lower contact and the corresponding groove of projection.
Adopt the sucker rod of said structure, be plugged on together by projection, groove between two sucker rods, box cupling is installed in the joint outside of two sucker rods, in the use, bear torsion by the projection, the groove that are plugged on together, therefore, can not thread off, twist off phenomenon, improved sucker rod application life, avoided causing sucker rod to fall into the down-hole and carried out problems such as down-hole salvaging because of threading off, twisting off.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is that the A of Fig. 1 is to partial view.
Fig. 3 is that the B of Fig. 1 is to partial view.
Fig. 4 is the schematic diagram of connected mode of the present utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.
As shown in drawings, the antitorque sucker rod of novel anticreep of the utility model, it has the oil pumping body of rod 4, and the oil pumping body of rod one end is the lower contact 3 of band external screw thread 2 for top connection 5, the other end of band external screw thread 6, projection 7 is arranged in the top connection, have in the lower contact and the corresponding groove 1 of projection.
As shown in Figure 4, when connecting between the sucker rod, the projection in next root sucker rod top connection injects in the groove of a sucker rod lower contact, is installed together by screw thread on the upper and lower joint and box cupling 8 again.In the use, the projection, the groove that are plugged on together bear torsion, and pulling force, pressure are mainly born by box cupling, thereby have avoided pumping rod disengaging, twist off the generation of phenomenon.
